It looks like one of those double sided stainless steel sinks, but you kind of have to squint just right and stand on your left foot with you tounge stuck out to get a clear idea of it....Ok, that might not be entirely true, just my "point of view" I know that they say it is a sink and if you look on the internet where they are showing the little frozen picture of it you can tell it is a sink, but as far as sitting in a theatre staring at a screen...It's a bit hard to distinguish from any other type of streaking debris. And thats my 31 times having seen it talking here. Maybe it will still be showing tomorrow night, I wouldn't be against seeing it again. That is, if I get home and if I feel like it.
